WARNING
For installation, adjustment and replacement information of the products not found in the user's manual, please consult the place of purchase or a distributor. A dealer's manual for professional and experienced bicycle mechanics is available on our website (https://si.shimano.com).
For safety, be sure to read this "user's manual" thoroughly before use, follow it for correct use, and save it so that you can refer to it at any time.
The following instructions should always be followed in order to prevent personal injury, physical damage to equipment and the surrounding environment. The instructions are classified according to the degree of danger or damage that may occur if the product is used incorrectly.
DANGER - Failure to follow the instructions will result in death or serious injury.
WARNING - Failure to follow the instructions could result in death or serious injury.
CAUTION - Failure to follow the instructions could result in personal injury or physical damage to equipment and the surrounding environment.

WARNING
- Because each bicycle may handle slightly differently depending on the model, learn the proper braking technique (including brake lever pressure and bicycle control characteristics) and operation of your bicycle. Improper use of the bicycle's brake system may result in loss of control, which may lead to serious injury due to a fall or collision.
- Do not disassemble or modify the product. This may cause the product to malfunction, you may fall unexpectedly and be seriously injured.
- Before riding the bicycle, riders must get used to the higher performance of this brake. 220 mm, 203 mm and 180 mm disc brake rotors provide more braking power than 160 mm disc brake rotors. If you ride the bicycle without thoroughly familiarizing yourself with the braking characteristics, braking may result in falling off the bicycle with possible serious injury or fatal accident.
- Keep your fingers away from rotating disc brake rotors. The disc brake rotor is sharp enough to cause serious finger injury if fingers get caught in the moving rotor openings.
- Do not touch the calipers or disc brake rotor during or immediately after riding the bicycle. During braking, the calipers and disc brake rotor become hot, so you may get burned if you touch them.
- Do not allow oil or grease to get on the disc brake rotor and brake pads. Riding the bicycle with oil or grease on the disc brake rotor and brake pads may cause the brakes to malfunction and lead to serious injury due to a fall or collision.
- Check the thickness of the brake pads and do not use them if they are 0.5 mm or less in thickness. This may cause the brakes to malfunction and lead to serious injury caused by a fall or collision.
- Do not use the disc brake rotor if it is cracked or deformed. The disc brake rotor may break and lead to serious injury caused by a fall.
- Do not use the disc brake rotor if its thickness is 1.5 mm or less. Also, do not use it if the aluminum surface is visible. The disc brake rotor may break and lead to serious injury caused by a fall.
- Do not apply the brakes continuously. This may cause a sudden increase in brake lever engagement, cause the brakes to malfunction and lead to serious injury due to a fall or collision.
- Do not use the brakes if there is fluid leakage. This may cause the brakes to malfunction and lead to serious injury caused by a fall or collision.
- Do not apply the front brake too strongly. If you do so, the front wheel may lock and the bicycle may tip forward, causing serious injury.
- Because the required braking distance will be longer during wet weather, reduce your speed. Apply the brakes well in advance and gently. You may fall or collide and be seriously injured.
- A wet road surface may cause the tires to lose traction. To prevent this, reduce your speed and apply the brakes well in advance and gently. If the tires lose traction, you may fall and be seriously injured.
- For use with hydraulic disc brake type with dual control lever
- This hydraulic brake system has different braking characteristics than those of the rim brake type, indicating a relatively large braking force at the start of braking (higher than with the rim brake type); before use, become thoroughly familiar with the braking characteristics. If you ride the bicycle without thoroughly familiarizing yourself with the braking characteristics, braking may result in falling off the bicycle with possible serious injury or fatal accident.
- The braking force of the hydraulic brake system will increase along with the size of the disc brake rotor (140 mm, 160 mm, 180 mm, 203 mm).
- Do not use a 203 mm disc brake rotor. This will excessively increase the braking force, which may cause you to lose control of the bicycle, fall and be seriously injured.
- Only use a 180 mm disc brake rotor if you cannot obtain sufficient braking force with a 160 mm disc brake rotor during a test ride, such as when riding a road e-bike or if the rider is heavy. Otherwise, you may lose control of the bicycle, fall and be seriously injured.
- If you feel the braking force is too great or too small, stop using it and consult the place of purchase or a distributor. Accidents or falls may occur due to loss of control of the bicycle, which may result in serious injury.

CAUTION
- Warnings regarding SHIMANO genuine mineral oil
- In case of contact with eyes, rinse the eye with clean water and seek immediate medical attention. Contact with eyes may cause irritation.
- In case of contact with skin, wash it thoroughly with soapy water. Contact with skin may cause rashes and difficulties.
- Protect your nose and mouth with a protective breathing mask and use in a well-ventilated room. Inhaling mineral oil vapor or fumes may cause nausea.
- After inhaling mineral oil vapor or fumes, immediately go to a place where there is fresh air. Cover yourself with a blanket. Stay warm in a stable position and seek professional medical attention.
-Warm-up time
- Disc brakes have a certain warm-up time, and the braking force gradually increases along with the increasing warm-up time. Accidents or falls may occur due to loss of control of the bicycle, which may result in serious injury. The same situation occurs when replacing brake pads or the disc brake rotor.
